I got 3/4 tank of gas in my car I need it for my wife car, how do I syphon gas

with a hose in your tank below gas level have a gas can ready,suck on hose to get it started then let if flow into gas can. make sure the can your filling is lower than your fill spout.then put gas in her car. good luck. do NOT GET GAS IN YOUR MOUTH.BE VERY CAREFUL.
